MOSCOW, Dec. 16 (Xinhua) -- Russian Foreign Minister Sergey Lavrov on Monday slammed Europe as a "quack doctor" for missing opportunities to help resolve the Ukraine crisis, while expressing optimism over recent engagements with the United States.

In an interview with Iranian media, Lavrov reiterated Russia's position that the root causes of the conflict must be addressed, including NATO's eastward expansion, Ukraine's potential NATO membership, territorial disputes and security guarantees.

Lavrov said that Europe has repeatedly turned a blind eye to efforts to resolve the crisis, using the situation instead to strengthen its own position and obstruct attempts by the United States and other parties to reach a fair settlement.

Likening Europe's approach to that of a "quack doctor," he said, "They only prescribe medicines that make you feel better for five minutes. They will never make a proper diagnosis."

Lavrov also pointed to recent U.S. contacts as a positive development, noting that the United States now better understands Russia's stance and recognizes the need for a lasting resolution, not just a temporary ceasefire followed by continued arms supplies to Ukraine.

Relevant processes are moving forward, Lavrov added, "and we are awaiting the U.S. response regarding U.S.-Ukraine talks." Enditem
